I'm quite happy on how my 530 performs with firmware 7.10 and would like to block updates to it, but cant find that option? Does that option not exist in Edge as it does in a Forerunner?
after a file has been uploaded to your device, you can cancel the installation. how do you know, you will not like the next version? how did you know that you will like 7.10 before installing?
My guess is- using only Bluetooth and never connect your edge to the laptop or wifi anymore.. then you will receive no updates anymore, but also no map updates as well
Can you read? What I wrote blocks updates and does not deprive you of any form of Edge communication with your phone.... Why complicate your life when there is a simple and effective solution
